RV082: Connections not in log

From a client behind RV082 I run FTP PUT in passive mode to a server. RV082 is setup to log â€œeverythingâ€ both in its own logs and to an internal Linux machine. In the logs I can see the ACCEPT entry when the client connects to the server on FTP control connection (to port 21). I would also expect an ACCEPT entry for the data connection when doing PUT. No such entry appears in the logs. Can anyone explain whatâ€™s going on here? Or rather in the router?
